It is commonly used as an eye drop during pediatric eye examinations to dilate the eye and prevent the eye from focusing/accommodating (cycloplegic). Cyclopentolate [citation needed] or atropine can also be administered to reverse muscarinic and central nervous system effects of indirect cholinomimetic (anti-AChase) administration.
Dilated fundus examination (DFE) is a diagnostic procedure that uses mydriatic eye drops to dilate or enlarge the pupil in order to obtain a better view of the fundus of the eye. [1] Once the pupil is dilated, examiners use ophthalmoscopy to view the eye's interior, which makes it easier to assess the retina , optic nerve head , blood vessels ...
